勒紧缰绳

Text:

选择一项～
•直到回合结束，获得目标生物的操控权，且该生物获得敏捷异能。
•牺牲一个生物。勒紧缰绳对目标生物或牌手造成伤害，其数量等同于所牺牲生物的力量。
打包（如果你支付打包费用，则两项都选择。）

Rulings:

• 12/1/2004 If you pay the entwine cost, you can sacrifice the creature you gain control of with Grab the Reins.
• 12/1/2004 If you choose the “sacrifice a creature” mode, you choose the target of the damage on announcement, but don’t choose what to sacrifice until resolution. You must sacrifice a creature when Grab the Reins resolves, even if you don’t want to. If you don’t control any creatures at that time, Grab the Reins deals no damage.
• 12/1/2004 If you cast this with Entwine, you don’t get priority in the middle of resolution. You can’t steal something, do anything (like attack with it), and then sacrifice it.
